ELAPSED TIME RECORDER BACKGROUND OF THE INVENTION This invention relates in general to time recorders and deals more particularly with an improved time recorder for providing a printed record of elapsed time for direct read out.

Most conventional attendance time recorders provide a record of time at the beginning and end ofa time interval. Time recording devices of the latter type are commonly employed in parking facilities, industrial plants and the like where the data ultimately desired is a function of elapsed time computed at an hourly rate. The need for practical apparatus for directly recording elapsed time to simplify computation of hourly cost is well recognized in the art. Apparatus heretofore provided for recording elapsed time has usually included a pair of operating handles or the like one of which must be operated at the start of a time interval and the other of which must be operated at the end of the interval. Such apparatus may introduce possible operational error and is unduly complex and expensive to manufacture and service.

The general aim of the present invention is to provide an improved elapsed time recording apparatus which is simple to operate and may be manufactured and serviced at low cost. A further aim of the invention is to provide an improved unitary elapsed time recording mechanism compatible with various existing attendance time recording apparatus lacking a direct elapsed time recording feature and which may be readily incorporated in such recording apparatus without substantial change in the design of the recording apparatus.

SUMMARY OF THE INVENTION In accordance with the present invention an improved elapsed time recorder is provided which comprises a card receiver for supporting a record card in one position and in another position displaced from said one position and a pair of rotable printing dies driven in accordance with passage of time an spaced apart in the direction of and at a distance substantially equal to card displacement. One of the dies has time graduations thereon and the other includes a reference mark. The recorder also has means for printing indicia from at least one of the dies when the card is in one of its positions and for imprinting indicia from at least the other of the dies when the card is in its other position, so that the resulting imprints are in registry and provide a composite imprint which indicates elapsed time between imprints for direct read out.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Turning now to the drawings, a preferred embodiment of the invention is illustrated and described with reference to a time recorder or time clock designated generally by the reference numeral 10 and shown with the cover removed therefrom. The illustrated recorder 10 is an attendance time recorder of a type manufactured by Lathem Time Recorder Company, Atlanta, Georgia, designated 8800 Series, particularly adapted to provide a printed record of time at the beginning and end of a time interval, as for example, times of arrival and departure, and modified to embody the invention.

The recorder 10, as provided by the manufacturer, includes a frame 12 which has a movable card receiver 14 mounted thereon for receiving and supporting a record or time card 16 inserted thereinto. The recorder 10 also includes an exact time recording mechanism indicated generally at 18 for printing exact time in standard units on the card 16 at the beginning and end of the time interval to be recorded. The card holder 14 is adapted to hold the record card in first and second po sitions and is supported on the frame 12 for horizontal movement relative to the recording mechanism 18 between the latter two positions. A clock 20 positioned at the front of the recorder, as it appears in FIG. 1, has a dial which is visible through an opening in the front of the cover (not shown).

In accordance with the present invention, the recorder 10 also includes an elapsed time recording mechanism indicated generally at 22 which comprises a pair of rotatable printing dies respectively designated by the numerals 24 and 26 which rotate in accordance with passage of time. The die 24 has indicia of time thereon. The other die 26 includes indicia of time reference. The dies 24 and 26 are spaced apart in the direction of card displacement a distance substantially equal to the distance between the first and second positions of the card 16. At least one of the dies is adapted to form an imprint on the card in its first position and at least the other of the dies is adapted to form a second imprint on the card in its second position. Since the distance between the dies 24 and 26 as measured in the direction of card movement is substantially equal to the distance between the first and second positions of the card it will be evident that the resulting die imprints on the card will be in registry. The composite imprint formed by the two dies provides a printed record of elapsed time for direct read out.

The time card 16 is particularly adapted to receive time imprints in adjacent vertical columns designated Start and Finish and composite imprints of elapsed time in another vertical column headed Elapsed Time. Additional columns may be provided on the card to receive other information to be filled in by the user as, for example, the quantity of items manufactured during a given time interval. A typical time card 16 is shown in F IG. 7 as it appears after it has been inserted into the recorder 10 a plurality of times. Start and finish time imprints are respectively designated as S and F. A composite imprint of the dies 24 and 26 is designated by the letter E and indicates the elapsed time interval between times S and F. At E an imprint of the reference die 24 is shown which has been formed on the card 16 at the start of the next time interval to be recorded.

Considering now the recorder 10 in further detail, the frame 12 is formed from a plurality of plates welded together in assembly. More specifically, the frame includes a base plate 28, a top plate 30, and a pair of transversely spaced vertically disposed side plates 32 and 34 which connect the base and top plates. Another vertically disposed plate 36 positioned forwardly of the side plates further connects the base and top plates.

The card receiver may take various forms but preferably, and as best shown in FIG. 4, the receiver 14 includes a bell-mouthed upper end portion 38 which defines a card receiving slot. A pair of opposing vertically disposed channels 40 and 42 depend from the upper portion 38 to receive and compliment associated marginal edge portions of the card 16 and guide it along a predetermined vertical path when it is inserted into the card receiver. The card receiver 14 also has a thin mask or shield 44 mounted at the upper left side thereof which covers an associated portion of the face of the card 16 received therein. A circular opening 46 formed in the mask 44 exposes an associated portion of the card face. Rods 48, 48 extend transversely between the plates 32 and 34 rearwardly of the card receiver 14 to support it for horizontal sliding movement relative to the frame 12 between first and second positions respectfully indicated by full and broken lines in FIG. 4 respectively corresponding to the first and second positions of the card 16.

Considering now the time recorder mechanism in further detail, the exact time recording mechanism 18 comprises a type wheel assembly indicated generally at 50. It includes a plurality of type wheels journalled in adjacent relationship for rotation about a horizontal axis parallel to the face of the card 16 between a pair of connected plates 52 and 54. The plate 54 is hinged at the forward end of the plate 36 to pivot about a vertical axis so that the type wheel assembly 50 may be pivoted to an open position clear of the top plate 28, as indicated by broken lines in FIG. 1 and removed from the frame 12, if desired, for convenient servicing. A synchronous motor 56, operably connected to the type wheel assembly 50 by a clutch mechanism when the type wheel assembly is in its operating position on the frame, indexes the type wheels in accordance with passage of time in a manner well known in the art. The motor 56 also drives the clock which is connected of the type wheels has a circumaxial series of time graduations on the peripheral surface thereof which are disposed in close proximity to the face of the card 16 when it is positioned within the card receiver. A ribbon feed mechanism of conventional type, which for clarity of illustration is not shown, cooperates with the type wheels to apply ink imprints to the face of the card.

The recording mechanism also includes horizontally elongated platen 60 which cooperates with both the exact time recording mechanism 18 and the elapsed time recording mechanism 22 to form imprints on the card 16. The platen 60 is supported rearwardly of the card receiver 14 in alignment with the type wheels, at a point where the type wheels are generally tangent to the card 16 for movement generally toward and away from the type wheels. More specifically, the platen 60 comprises an elongated bar mounted on a pair of horizontal rods 62, 62 which are supported for sliding movement by and extend through a support member 64 which extends transversely between the plates 32 and 34. A lever assembly indicated generally at 66 includes a pair of levers 68, 68 connected together to pivot in unison about a support rod 70 which extends transversely between the plates 32 and 34. Each lever 68 has a slot formed in its upper end which receives a bent end portion of an associated rod 62. The lower ends of the lever assembly 66 is connected by a linkage 72 to the armature of an electric motor or solenoid 74 mounted on the base 28. Operation of the solenoid as hereinafter further described pivots the lever assembly 66 to move the platen 60 into striking engagement with the rear surface of the card 16 to cause the type wheels and dies to form an imprint on the front surface of the card.

Considering now the elapsed time mechanism 22 in further detail, in accordance with the invention, the dies 24 and 26 comprise a pair of disks of substantially equal size as best shown in FIG. 5. The disk 24 has an annular series of time graduations on the face thereof. As shown, the disk 24 has uniformally spaced numerical graduations from 0 to 5, each numerical graduation representing l hour of elapsed time. The angular space between adjacent numerical graduations is divided into equal parts, each part representing a 6 minute interval of elapsed time. Thus, in the illustrated recorder 10, the disk 24 is adapted to make one complete revolution every 6 hours, however, it should be understood that other arrangements of time graduations may be provided and are contemplated within the scope of the invention. The disk 26 has a radially disposed time reference mark 76 on the face thereof, and is arranged to rotate in unison with the disk 24 in the same direction and at the same rate. The disks 24 and 26 are journalled for rotation about parallel axes normal to the face of the card 16 and are carried by a bracket 78 mounted on the plate 52. The faces of the disks are dis posed in substantially the same plane and in close proximity to the face of the card 116 when it is positioned in the card receiver. The disks 24 and 26 may, if desired, be driven by the motor 56, however, preferably and as shown, an individual synchronous drive motor 80 is provided which drives the disks through an associated gear train 82 as best shown in FIG. 3. Thus, the elapsed time recording time mechanism 22 comprises a unitary structure which may be installed on any compatible time recorder and may be readily removed therefrom for servicing or replacement. The elapsed time recording mechanism 22 also includes an associated ribbon feed mechanism which has an inked ribbon 83, a portion of which is disposed between the face of the disks 24 and 26 and the card receiver 14. A ratchet and pawl mechanism (not shown) advances a ribbon 83 each time the recorder operates, in a manner well known in the art. The illustrated recorder has separate ribbon feed mechanisms for the exact time recording mechanism l8 and the elapsed time recording mechanism 22. However, it should be noted that a single ribbon feed mechanism may be provided which cooperates with both time recording mechanisms and such arrangement is contemplated.

The apparatus 10 is adapted to provide a record of a plurality of time intervals printed in vertical sequence on the card 16, as shown in FIG. 8 and for this purpose the recorder 10 includes a vertical indexing mechanism. The indexing mechanism, shown somewhat schematically in FIG. 6 and indicated generally by the numeral 84 includes a contact making lever 86 which is supported for vertical movement relative to the frame and carries a contact arm 88. The contact making lever 86 has an abutment 90 disposed below the card receiver 14 and in the path of the inserted card and is biased upwardly relative to the frame of the recorder by a light spring such as indicated at 92. It is arranged to be moved downwardly by the continued advance of an inserted card 16. When the card 16 is initially inserted in the card receiver 14, continued advance of the card causes the lower edge thereof to engage the abutment 90 thereby moving the contact arm 88 ito engagement with a switch 94 which energizes the solenoid 74 to operate the printing mechanism, as aforedescribed. A striker 96, carried by the lever assembly 66 operably engages a punch 98 which forms a perforation in the card 16 as indicated at 100 in FIG. 4. The indexing mechanism 84 also includes a sensing switch 102 for detecting the presence of a card in the card receiver. When the card is next inserted in the card receiver, the sensing switch 102 energizes another solenoid 104 which pivots a locating finger 106 into engagement with the front surface of the card 16 in vertical alignment with the punch. When the locating finger, which is carried by the contact making lever 86, finds the perforation 100 formed in the previous printing operation, the finger enters the perforation whereupon continued advance of the card causes downward movement of the locating finger 106, the contact making lever 86 and the contact arm 88 to energize the solenoid 74 and simultaneously print the next time registration and form the next perforation in the card. Upon completion of the printing cycle, a relay circuit or the like (not shown) associated with the solenoid 104 attains open circuit condition permitting the locating finger 106 to be biased to a normal position out of engagement with the card, whereupon the card may be removed from the card receiver.

Indexing mechanisms of the type generally aforedescribed are well known in the art. Disclosure of such a mechanism, suitable for use with the elapsed time recording mechanism of the present application, is found in U. S. Pat. No. 2,645,551, issued to Sprecker, July 14, 1953, for Time Recording Machine.

It is essential to the proper operation of the elapsed time recording mechanism that the disks 24 and 26 imprint on the card in overlapping registration to assure accurate indication of elapsed time. Accordingly, a means is preferably provided to disable the operating mechanism except when the card 16 is in one of its record receiving positions. In the illustrated embodiment 10, the disabling means comprising a pair of micro switches 108 and 110 mounted on the frame 12 in the path of the card receiver 14 as shown in FIG. 4. The switches 108 and 110 are each electrically interlocked with the operating switch 94 so that the latter switch cannot energize the solenoid 74 unless the card receiver is in either of its imprint receiving positions.

Considering now the operation of the recorder 10, at the start of a time interval to be recorded the card receiver 14 is shifted to its first position or full line position of FIG. 4. In the latter position the die 26 is aligned with the opening 46. When the card 16 is inserted into the card receiver the lower edge of the card engages the abutment 90. Further advance of the card causes the contact arm 88 to actuate the switch 94 whereupon an imprint of the time reference die 26 is formed on the face of the card in the column headed Elapsed Time" as shown-in FIG. 7. The exact time recording mechanism l8 simultaneously imprints the exact starting time of interval indicating the day and the time in standard hours and minutes in the column headed Start. At the end of'the time interval to be recorded, as for example, upon completion of a job, the card receiver 14 is shifted to its second position whereupon the printing mechanism is again automatically actuated by insertion of the card as previously described. The die 24 is now aligned with the opening 46 and forms an imprint on the card 16 in overlapping registration with the imprint previously formed by the time reference die 26. The exact time of the finish of the interval is simultaneously imprinted on the card in the Finish" column in horizontal alignment with the imprint of the starting time. Thus, with reference to FIG. 7, it will be noted that the first recorded interval, which appears near the top of the card 16, started at 8:48 and ended at 10:10 oclock. The position of the reference mark 76 in the column indicated Elapsed Time shows an elapsed time of 1 hour and 12 minutes. Perforations (not shown in FIG. 7) have been formed in the card during each of the latter recording operations. Thus, when the card 16 is next inserted in the card receiver, the indexing mechanism 84 previously described operates to locate the card so that the next imprint of the time reference die 26 is positioned below the previously formed composite imprint, as indicated at E and S in FIG. 7.

Refering now particularly to FIGS. 8 and 9, another time recorder embodying the invention is indicated generally by the reference numeral 10a. The recorder 10a is similar in most respects to the recorder 10, previously described and parts which correspond to parts previously described bear the same reference numerals as the previously described parts and will not be hereinafter further discussed. The recorder 10a includes a modified form of unitary elapsed time recording mechanism 22a, and in this respect it differs from the recorder previously described. The construction and arrangement of the card receiver 14a, shown in FIG. 9, also differs somewhat from the card receiver 14 of the previously described recorder 10. The recording mechanism 22a is particularly adapted for use with a vertical print recorder wherein sequential records of time are imprinted in vertical series on a record card such as indicated at 16a.

The unitary elapsed time recording mechanism 22a is similar to the mechanism 22 previously described in that it includes a mounting bracket 78a supporting a pair of rotable dies 24a and 26a, a drive motor 80a and a gear train 82a providing driving connection between the motor and the dies. However, it will be noted that the dies 24a and 26 are mounted in vertically spaced relation to each other. The dies 24a and 26a are supported in axially normal relation to the plane of the card receiver 14a with the faces thereof disposed in substantially the same plane and in substantially the same relation to the card receiver as in the previously described embodiment 10. The bracket 78a is releasably secured to the plate 52a by suitable fasteners to facilitate removal for servicing.

Referring now to FIG. 9 and considering the card receiver 14a it will be noted that it is generally similar to the card receiver previously described, but does not include a shield. The receiver 14a is mounted in a fixed position relative to the frame by a pair of collars 112, 112 secured to the upper rod 480. Thus, the receiver 14a defines a predetermined vertical path of travel for the card 16a.

The recorder 10a includes a vertical indexing mechanism identical to the indexing mechanism 84 shown in FIG. 6. However, the vertical spacing between the punch 98 and the locating finger 106 is substantially equal to the vertical spacing of the dies 24a and 26a so that sequential imprints of the dies will be in registry.

It is also desirable that the recorder 10a include a disabling mechanism to prevent the printing mechanism from operating to form an imprint on the card except when the card is in one of its printing positions. A manual operating button 114 is provided and interlocked with the switch 94 associated with the vertical indexing mechanism 84 for this purpose. More specifically, the latter interlocking arangement is such that the card 16a must be inserted into the card receiver 14a to actuate the switch 94a before the operating button 114 can be actuated to operate the printing mechanism.

The printing mechanism is substantially identical to the printing mechanism of the previously described recorder 10, however, the area of the platen may be somewhat enlarged in the vicinity of the dies 24a and 26a to assure full printing cooperation therewith.

A typical record card 160 is shown in FIG. 10, as it appears after having received one complete imprint of elapsed time formed by two printing cycles of the recorder 1011. Initial full insertion of the card 16a into the receiver 14a causes the dies 24a and 26a to imprint thereon as respectively indicated at E and E An imprint of starting time is also formed on the card at S, and an indexing hole 100a is simultaneously punched in the card. When the card 160 is again inserted into the receiver the finger 106 enters the hole 100a to position the card for further printing, so that the next imprint of the die 24a occurs at E in overlapping registry with the imprint of of the die 26a formed by the previous printing cycle. Thus a composite imprint of the dies 24a and 26a occurs at E to provide direct indication of elapsed time. Another imprint of the die 26a is simultaneously formed therebelow at E An imprint of finish time is also made on the card at F, and another indexing hole 1000 is also simultaneously punched in the card 16a for cooperation with the indexing mechanism to position the card to receive the next imprint.

It will now be evident that the recorded time F, FIG. 10, which designates the finish time of elapsed time interval E also designates the starting time of the next interval E Thus the time recorder 10a provide an uninterrupted record of time.
